Reef Factory Smart Roller Plumbing

[tymo92]

I’m planning plumbing for my 230G I’m building and will have a Reef Factory Smart Roller M hooked up to my main drain which is 1.5” schedule 40.

The inlet for the Roller is 40mm metric. My question is how can I connect my 1.5” drain to the 40mm inlet while not reducing the plumbing diameter and flow rate?

The roller comes with an adapter but it reduces down to 1” which I want to avoid. Planning to run a lot of flow into the Roller.

Imperial plumbing is measured by inside diameter.

Metric plumbing is measured by outside diameter.

This means there will be no way to avoid restriction when adapting to 40mm pipe…

That is helpful. How would you plumb it to minimize restriction as much as possible?

Is is physically possible to increase the inlet size of the roller mat, even by cutting/drilling/grinding/pipe cementing? That would be the proper way in my experience…

Can you share a photo of what the inlet to the roller looks like? I’m unfamiliar with this specific model!

May be able to do that. Here’s what the inlet looks like, with the 40mm to 1.25” adapter on top the ruler.

Hmm… that looks awful tight for a 1.5” bulkhead…

I used bulk reef supply .. they sell a union that explicitly goes from 40mm to 1.25in on the other side.

And do not make the initial mistake I did.. doing bean animal and wye-d (1.25in) the primary drain(1") and secondary(1in) together going into reef factory roller. The flow from the primary created vacuum on secondary such that always sucking sound.. so had to separate them and not fleece filter the secondary

Good advice on not tying the primary and secondary together into the roller…

The roller came with that 40mm to 1.25” adapter but I want to avoid reducing that much. 40mm is 1.57” and my drain is 1.5”. I need to find something that fit outside the roller inlet ideally.

It should also be mentioned that metric plumbing is measured by OD, whereas imperial plumbing is measured by ID!
